Homojunction perovskite solar cells: opportunities and challenges

چکیده
Organometallic halide perovskites have rapidly become promising materials as a result of their outstanding properties in high-efficiency and low-cost next-generation solar cells. Perovskite can be adjusted to p- or n-type by defect engineering through, for example, the self-doping method controlling precursor compositions process conditions. Recently, p-type perovskite/n-type perovskite homojunction has been proposed constructed, which provides possibility design novel type cell (PSC). Following brief overview physical fundamentals homojunctions, detailed discussion progress recently reported PSCs is presented here, including theoretical simulations, extrinsic interfacial doping graded structures. Furthermore, opportunities regarding higher concentrations, simpler device architectures, ion migration inhibition stability are discussed. Finally, an outlook that offers insights into future development highly efficient stable provided.

Two-dimensional hybrid perovskites are used as absorbers in solar cells. Our first-generation devices containing (PEA)2(MA)2[Pb3I10] (1; PEA=C6H5(CH2)2NH3 , MA= CH3NH3 ) show an open-circuit voltage of 1.18 V and a power conversion efficiency of 4.73%. The layered structure allows for high-quality films to be deposited through spin coating and high-temperature annealing is not required for devi...
